POSSIBLE CAUSE #2 - Servo motor failure
CORRECTIVE ACTION
- If servo motor failure is suspected, the first step is to confirm that the
electrical connections at the servo motors are fully connected to the servo motors (there is a pos-
sibility that they are not fully 'snapped' into motor's connector).
If the connection is viable, verify that the three-wire connector is delivering the correct signal to
the motors. With the ignition switch turned to Accessory , unplug each of the servo connectors
and test according to the information in the Electrical Connection To Plenum Servo Motors
Diagram (Figure 4).
If the electrical check is in agreement with the Diagram and if the directional doors are not ob-
structed the likely problem is a failed servo motor.
Replace servo motor as required.
